You are an athlete.
Imagine that you are a professional soccer player. What steps would you take to make sure you played consistently at your prime without injury? You’d make sure your body was in shape. In order to have the right fuel for your body, you would monitor what you ate and make sure to eat healthily. To prevent injury, you would warm up before every single work out or game. You would also stretch before and after you played religiously. Part of your maintaining your health would likely include taking vitamins and supplements to ensure that your body had what it needed to be strong and replenish itself. If you wanted to build muscle and recover from training, you would want to sleep as much as possible. You would take breaks in between exercises and you would take days off so as not to overdo it. If you didn’t take all of these steps? You would get injured. You would be tired. You would not be primed to heal. If you didn’t warm up, you might pull a muscle. If you didn’t stretch after a workout, you would be sore. If you didn’t take time off, you would overdo it and injure yourself.
What do musicians do? We use our arms for hours on end. To be at our prime, we not only need to prepare physically, but mentally. We must have our body primed correctly for this type of muscle use, and we must take certain precautions to avoid injury, just like an athlete.
Get the point? If you are a musician, then YOU ARE AN ATHLETE.
